The greatest name man ever gave to God is Truth. Truth is the fruit of realisation; therefore seek it within the soul. Get away from all books and forms and let your soul see its Self. "We are deluded and maddened by books", Shri Krishna declares. Be beyond the dualities of nature. The moment you think creed and form and ceremony the "be-all" and "end-all", then you are in bondage. Take part in them to help others, but take care they do not become a bondage. Religion is one, but its application must be various. Let each one, therefore, give his message; but find not the defects in other religions. You must come out from all form if you would see the Light. Drink deep of the nectar of the knowledge of God. The man who realises. "I am He", though clad in rags, is happy. Go forth into the Eternal and come back with eternal energy. The slave goes out to search for truth; he comes back free.
